Question

样板房：

public class Room
    {
        public int Id { get; set; }
        public string NumberRoom { get; set; }
        public double CostPerNight { get; set; }
        public virtual Category Category { get; set; }
}

我的模型代码

public class RoomModel
    {
        public IList<Room> Rooms { get; set; }
    }

我的剃刀代码：

@model hotel.Models.RoomModel

@using (Html.BeginForm("ComfortLevelView", "Category"))
        {
            for (int i = 0; i < Model.Rooms.Count(); i++)
             {
                     <table class="simple-little-table" cellspacing='0'>
                         <tr>
                             <td>@Html.DisplayFor(m => Model.Rooms[i].NumberRoom) </td>
                             <td>@Html.DisplayFor(m => Model.Rooms[i].Categoryid)</td>
                             <td>@Html.DisplayFor(m => Model.Rooms[i].NumberOfSeats) </td>
                             <td>
                                 @{ var result = Model.Rooms[i].CostPerNight * numberNights; }
                                 <p>@ViewBag.NumberNights ночей</p>:@result
                             </td>
                             <td>
                                 <input type="submit" id="submit" value="Booking" />
                             </td>
                         </tr>
                     </table>
                 </div>
             }
        }

控制器：

public ActionResult ComfortLevelView(int NumberNights, int CategoryId, int NumberPeoples ,DateTime SelectedDate)
        {
            IRoomService roomService = new RoomService();;
            return View(roomService.GetRoomsByCategory(CategoryId, SelectedDate, NumberNights, NumberPeoples));
        }

[HttpPost]
public ActionResult ComfortLevelView(RoomModel model)
{
    //
}

传递到字典中的模型项的类型是＆＃39; System.Data.Entity.Infrastructure.DbQuery`1 [Hotel.BusinessObject.Room]＆＃39;，但此字典需要类型为＆的模型项＃39; hotel.Models.RoomModel＆＃39;

Answer 1

错误消息是不言自明的。你在视图中有这个

@model hotel.Models.RoomModel

但是由于控制器中的这行代码，您将System.Data.Entity.Infrastructure.DbQuery<Hotel.BusinessObject.Room>的实例传递给了您的视图

return View(roomService.GetRoomsByCategory(CategoryId, SelectedDate, NumberNights, NumberPeoples));

您需要传递RoomModel而不是System.Data.Entity.Infrastructure.DbQuery<Hotel.BusinessObject.Room>的实例。我建议将控制器代码更改为

public ActionResult ComfortLevelView(int NumberNights, int CategoryId, int NumberPeoples, DateTime SelectedDate)
{
    IRoomService roomService = new RoomService();
    var rooms = roomService.GetRoomsByCategory(CategoryId, SelectedDate, NumberNights, NumberPeoples);

    RoomModel model = new RoomModel();
    model.Rooms = rooms.ToList();

    return View(model);
}

对于每个提交表单的循环
